    adapt the suggestion to use XFetchName to work around a system whose locale

    Read system.twmrc from where it got installed

    ${rcdir} is ${datadir}/X11/twm by default, but can be overridden when
    running make.  If it is overridden, then the code should read from the
    same place as where "make rcdir=FOO install" puts the file.

    (Obviously overriding rcdir= for "make install" requires overriding it
    for "make" as well.  But at least this way it's possible to get it to
    work.  :-) )

    Remove custom version of system(3c) for Solaris

    Was originally added in 1993 with the comment:
     make f.exec do the right thing to get working xterms under Solaris2.

    Doesn't seem to be needed any more on modern Solaris.
    As a bonus, gets rid of error found by Oracle Parfait 1.5.1 that
    if the execl() call fails, the function falls through and returns
    an uninitialized value for status and then both parent & child
    go back to running the same code.

    Fix SEGV if CreateColormapWindow() returns NULL.

    twm can segfault when it cannot collect attribute information on
    a window that has been destroyed before it got a chance to collect
    it's attributes.
    twm seems to assume that it is always able to collect this information
    and disregards the error if the function that attempts to collect it
    fails and CreateColormapWindow() returns NULL.
    If this happens correct number_cmap_windows to prevent a SEGV later

    NOPUTENV was never defined in a modular build, probably because putenv()
    is a standard function in Unix98 / SUSv2, and goes back to at least

    As an interim measure, replace AM_INIT_AUTOMAKE([dist-bzip2]) with
    AM_INIT_AUTOMAKE([foreign dist-bzip2]). This will prevent the generation
    of the INSTALL file. It is also part of the 24206 solution.

    Use a unique token for PKG_CHECK_MODULES. Otherwise, if you use a global
        configure cache, you cache it, and the cached value is probably wrong.

    //bugs.freedesktop.org/show_bug.cgi?id=2705) attachment #2087
        (https://bugs.freedesktop.org/attachment.cgi?id=2087) Make twm ignore
        print screens to avoid that users accidentally warp on a non-video
        screen (which are not visible on any monitor) when the Xserver has both
        video and print screens. (This includes also a small cleanup of
        xdpyinfo where parts of the print screen test code comes from) Patch by
        Julien Lafon <julien.lafon@gmail.com> (MIT/X.org license).
